( represents a segmental shifting-plato ol the wear-platos E E and engaging in re! oossee or depressions ji, formed in opposite sides of the Shifting-plate G, so that by turning; the plate (l the wear-plates E E will be siinnlizinooimly ,Lhii'iod in opposite directions by moans ol' the Studs i.

The shifting-plate G is provided with a square projection g', to which n wrench may be applied for turning the plaie. Upon loosening; the clamping-bolts h the shifting-plate can 'lie turned so als to move the wedgesheped 'wear-pinion farther into the tapering spaces lnnwoen i'he cross-head and the guides b to take np any wozu of the plates. After the .\eoiplzLieS have been properly adjusted they :nre firmly hold upon the cross-head by tightening; the (clamping-boils 71 'the .Studs 'i holding the wozir-plziies :against longitudinal moveinout on the Cross-head by being sented in the recesses j. loih wear-plates are in this manner adjusted uniformly and evenly, thereby maintaining the Crosia-head in line with the pinion-rod :it all times and preventing binding oi' the parts.

'lho Conner'bing-rod D is provided zitornoar its ond with nn elongated opening or recess f, which is curved at itS out-er end, as shown ata, to form :i concave sont for one of the bi'nssozs or sections Z ol' the bushing which Surrounds Lilo journal d of the cross-head.

m ropros le follower or movable block arranged the 'recess 7a and provided with :i eenen 've sont `m, which bears against the other' section Z of the bushing.

An is fin adjusting-screw whereby the follower mis moved toward the journal d, and which engages with its Ithreaded front p0rtion in a threaded opening `n', [armed in the rear side of the follower m. The adjustingscrew n is provided with a nut. or collar o for turning the same, which hears against the 'inner wall ofthe recess lf, and whereby the screw is held against lengthwise movement. The inner rearportion of the adj usting-screw is preferably made smooth and fits in an open.

ingor socket o in the adjacent portion of the connecting-rod.

p is a jam-nut arranged on the adj ust-ingscrew `n and bearing against the rear endl ot the follower n1, so as to clamp the serew'in position after being adjusted. f

o2 represents a stud formed on the bushing Z and seated in an opening in the concave face ot' the connecting-rod D, wherebythe brasses which renders the rod strongandlight. The' usual projecting keys and gibs are 'dispensed with and a simple and reliable adjusting de*- vice substituted, which is especially desirable for the connecting-rods of traction-engines. I clai-m as my invention l. The combination, with the-pcross-head i provided with inclined faces, of adjustable wear-plates having inclined inner sides resting against the inclinedv faces of the cross-head and provided with studs or pins, anda shifting-plate attached to the cross-head and. pro

vided with recesses or depressions in which.

said studs engage, substantially as *set forth. 2. The combination, with Ithe cross-head provided with inclined faces, of adjustable wear-plates having inclined inner sides resty ing against the inclined faces of the cross-head and provided with studs or pins, a shittingplate provided with recesses or depressions in which said studs engage and with curved slots, and clamping-bolts passingthrough said slots and whereby the shifting-plate is secured to the cross-head, substantially as set forth. i fitness my hand this 21st day of September, lSSS.
